I have downloaded your project, open and closed it : no problem at all.Just some things : - how did you get to display those arrows at your tab positions ?? - did you ever try to start with a clean default.conf (delete it) ??

Otherwise, I can confirm that C::B crash with the las build (03/31/2006) with wx2.6.3Take again my project and open it in C::BIf Breakpoints and Watches windows are not opened then open them.You should have a screen like thisQuit C::B. When C::B ask you for saving layout, click on Yes
